Abstract

Aims

Spinal cord stimulation (SCS) is a treatment for patients with refractory angina pectoris (RAP) who remain symptomatic despite optimal medical therapy and without revascularisation options. Previous studies have shown that SCS improves the quality of life in this patient group and reduces the severity of the angina pectoris. The aim of this prospective, single-arm observational study is to show this effect in a single-centre cohort using a multidisciplinary team approach to the selection process, with a follow-up period of 1 year.

Methods and results

Between July 2010 and March 2017, 87 patients with RAP referred to our centre received SCS. The Seattle Angina Questionnaire (SAQ) and RAND 36-Item Health Survey (RAND-36) were completed at baseline, prior to implantation, and 1 year post-implantation. After 1 year of follow-up there was a statistically significant decrease in the frequency of angina pectoris attacks from more than 4 times a day to 1–2 times a week (p < 0.001). The SAQ showed statistically significant improvement in four of the five dimensions: physical limitation (p < 0.001), angina frequency (p < 0.001), angina stability (p < 0.001) and quality of life (p < 0.001). The RAND-36 showed statistically significant improvement in all nine dimensions: physical functioning (p = 0.001), role/physical (p < 0.001), social functioning (p = 0.03), role/emotional (p < 0.05), bodily pain (p < 0.001), general health (p < 0.001), vitality (p < 0.001), mental health (p = 0.02) and health change (p < 0.001).

Conclusion

This study showed a significant improvement in quality of life and reduction of angina pectoris severity after 1 year of follow-up in patients treated with SCS for RAP.
